It won't be completely the same as git, because the client fetches stuff more lazily (according to the linked presentation). So the backend will still fill up with stuff and need lots of storage, but the clients then won't necessarily slow down in the same way.

That said, any git users will still get slowed down - only jj users would see the benefit. Git does have better features these days for shallow clones though and even git is on the way to killing off the need for LFS.
